You work for a company that makes ice cream. They are the hottest days of the year and they have received orders for a quantity they cannot meet current materials and your suppliers do not give you an answer. Their products are very good and not having a flavor does not stop the sale of the others, that is, people come for their favorite flavor but, if there is not in stock, buy another. There are 3 flavors: Chocolate, Vanilla and Banana. They basically use the same ingredients for manufacturing. The profit generated for each gallon sold is $ 10, $ 9.0 and $ 9.5 respectively. The company has just 200 gallons of milk, 150 pounds of sugar and 60 gallons of cream this month to try to keep up with demand. (Everything is per gallon of ice cream) Chocolate is used: 0.45 gallons of milk, 0.50 pounds of sugar and 0.10 gallons of cream. The vanilla one uses: 0.50 gallons of milk, 0.40 pounds of sugar and 0.15 gallons of cream. And the banana one uses: 0.40 gallons of milk, 0.40 pounds of sugar and 0.20 gallons of cream. Additionally, you know that the owner's mother called and made a special order that will pay at a regular price, she needs 14 gallons of chocolate, at least 30 vanilla and at least 16 banana, to be sent home, and in total she should receive 70 gallons. This order is the first to come out and does not compete with other consumers so it is sure to be fulfilled, delivery does not depend on your model, only production.
